Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.

BackgroundIt has been proved that,after being forced,the biological soft tissue has stable biomechanical characteristics.However,there is rare study on corneal biomechanics.Rabbit is a main animal for experimental study in ophthalmology.But the biomechanical study of cornea in normal rabbit has not been reported.ObjectiveThis study was to investigate the biomechanical properties of normal rabbit central cornea and acquire the parameter. Methods Ten rabbits were sacrificed and the whole corneas were obtained and 20 central cornea specimens with 7 mm×5 mm of rabbit were prepared and tested on BOSE electroforce 3220-AT biomechanics machine under the room temperature and suitable humidity environment.Uniaxial tension,stress between strain,relaxation and creep were performed and the curves were drawn.The data was collected by wintest system to evaluate the biomechanical parameters of rabbit corneal tissue. ResultsThe maximum distortion intension of rabbit cornea was (7.7432±0.6099)MPa.After three cyclic loading,the stress gradually attenuated and the stress and strain flattened as the time change with the relaxation rate 30.33％.The deformation of the specimens enhanced with time decrease with the creep rate 24.33％. ConclusionsThe biomechanical characteristics of normal rabbit cornea are revealed in this study,which offer the basis for the experimental research of rabbit model aimed at corneal disease.
